    Very slow comcast internet please help!

    I have been having problems on and off with my internet for 2 years. I've had about 10 techs come out. The last time they came out i told them my upstream powel level was low and they fixed that. The other 9 times they came out they pretty much told me i was lying and my internet was perfect . As of right now I'm getting about 1mb down. The internet works great for a few days then back to the problems.

    Any help of what might be causing my problem would be great. I don't believe it is my modem since this is my 4th one in two years. Thanks!

    What problems exactly? Just slow speeds? Post a few speedtest results from www.speedtest.net be sure to copy and paste the forum codes into the reply so we can see the full graphic.
